The Effect of Nano Cement on the Compressive Strength of Coconut Fibers Reinforced Concrete Composite

Abstract

The development of nanotechnology continues to grow. The use of nanocement in concrete is expected to reduce the number of pores and improve hydration in concrete and provide more strength to the concrete. The use of natural fibers, in this case, coconut fiber can prevent cracks in concrete and make fiber concrete more ductile than ordinary concrete. The effect of using nanocement on coconut fiber concrete on the strength of the concrete to be studied. Methodology to complete the research objectives, use nanocement used in concrete, which has added coconut fiber. Tests reviewed the value of slump and specific gravity. Then, testing the compressive strength at 7, 24, 28 days. The results obtained were an increase of 48.19% in the strength of concrete. Further research needs to review on mixing nanocement with other natural fibers.

Water Absorption Rate in Porous Concrete Paving Block as a Permeable Pavement Structure

“…The compressive strength values of the three samples have different thicknesses, but the compressive strength values are almost exact (figure 6). This result is in accordance with previous research, which stated that paving block tests using the cube test produced more realistic values [20]. This fact also occurred in the compressive strength test of porous paving blocks (figures 7 and 8).…”
